r The invention relates to louver door strucut-ures; and :has for itsobject to provide a device 'of this character'wherein the louver is same time forming awfinish for theends of .:the louvers.

eiA -f urther-objectis to disposethe edges of uthepanels in achannelof a molding, which -"laamol-ding. has an interlocked engagement with amember-carried by the stiles and rails of the door, thereby 'allowing the panel with the louvers therein ito beieasily anctquickly asrsen1bled within the door:asa panel unit.

H120 further obj ect-is itQ= provide the ends of the :louvers with centrally disposed extension arms :in :vertical planes, which arms extend het-ween the; panel plates'andra're secured 1 'therreto, :for instance; by spot welding.

A further object is to provide theinner wedges of the panel plates withioppositely exi ctending angle, 1 portions, which portions vrezinforcethe inner edgesofithe panel andalso form .a: marginal frame for the. plurality of louver slats.

i A further object is to provide louver slats having vertical portions and upwardly. and downwardlyiinclined flanges terminat ng in upwardly and'downwardly extendlng flanges i= in verticalplanes whereby when said slats :are placed in overlappedrelation a maximum ventilating spaceis formed therebetween, and :one. WlliClT'W'llh. direct air upwardly to. 'one side of the louver or downwardlyat theother in its passage through the louver.

ith the above and otherobjects inview the invention resides inthe combination and arrangement of parts as hereinafter set forth, :shown in the -draWing,-descr-ibed.and claimed,

web it being understood that-changes -in the pre- -:c-ise embodiment of the invention may be "madevwithin the scopeuof what is claimed without departing-from the-spirit of the invention.

Figure 1 is aview in elevation of the door,

showing the louver applied thereto. 1

a Figure 2 is aperspective sectional view taken on line 2 of Figure 1.

Figure 3 is a horizontal sectional view through the side of the door taken on line 3 of Figure 1.

Figure 4 is a; perspective View of oneend of-one of the louver slats.

Referring to the drawing,-the numeral 1.v

designates the stiles of the door and 2 the rails thereof. Mounted on-the rails and stiles is a sheet metal molding'3, which molding is provided with a channel 4, which extends into the rails and stiles and is held between... I spring flanges 5 of the channel members 6 carried by the rails and stiles, there being an interengagement at 7. I Disposed within the channel: member 4 is the panel 8 which-carries the louver. Therefore it will be seen that the louver and panel are formed as a single unit to be assembled in the door. The panel 8 comprisesregistering plates 9, preferably having a metallic covering 10, and the inner edges of said plates 9 are provided with outwardly extending flanges 11 terminating in inwardly extending flanges 12, thereby formmg right angled members extending in opposite d1rect1ons on opposite sides of 'the panel. The lower louver slat 13 is provided with an extension flange 14, which is disposed between the panel plates 9, and is secured th'erebetween for instance by spot welding at 15, therefore it will be seenthatthe louver slat13 will be rigidly held. "The intermediate slats 16 have their central vertically disposed portions 17 provided with extensions l8,'which extensions extend between the plates 9 of the panel at the sides thereof, and "are securely held. in place by spot welding.

at 19, therefore it will be seen' that the ends of the'slats are rigidly held. The upper'and lower edges of the vertical portions 7 of the intermediate slats16 terminate in upwardly and downwardly inclined flanges 20, which extend towards the flanges 12 of thepanel and are provided with upwardly and downwardly extending vertical flanges 21, which engage the inner sides of the flanges 12, and

maybe secured thereto by spot welding if so desired. The flanges 20 and 21 have their ends in abutting engagement with the flanges 11 carried by the panel plates 9, therefore it will be seen that the ends are concealed from view, are rigidly braced and the flanges 12 form a finish for he louver of the door, which does not detract from the appearance of the door as is obvious by referring to Figure 1.

he lower louver slat 18 at its upper edge terminates in an upwardly and outwardly inclined flange 22, which in turn is provided with a vertically disposed flange 23 in the same vertical plane as the slat: flange 21, therefore it will be seen that the slat flanges .21 and 23 are in parallel planes which will not only add depth to the louver as a whole, but will also form air passages which will deflect air upwardly and downwardly into and out of a room, but will exclude or prevent a person-from seeing through the louver into a room. a

From the above it will be seen that a door is provided with a panel carried louver, which may be easily and quickly assembled within the metallic door and which panel may be received in the usual metallic molding of doors of this character, thereby allowing the units to be assembled in the doors during construction in the same manner as a conven tional form of panel.

The invention having been set forth what is claimed as new and useful is l. The combination with a metallic door frame, a panel disposed in said frame, said panel being formed from registering plates, a plurality of louver slats having their ends secured between the registering plates, and angular flanges extending from said slats.

2. The combination with a metallic door, a panel molding carried thereby, a panel disposed in said molding, said panel comprising registering plates, louver slats, said louver slats having portions extending between the registerin plates of the panel and secured thereto, oppositely :rtending angular flanges carried by the plates, said louver slats having offset flanges in vertical planes engaging the angular flanges of the plates.

3. A metallic door structure comprising a frame, a molding carried by said frame, a panel having a louver opening therein, said panel being formed from registering plates disposed in the molding, the inner edges of said registering plates being provided with outwardly and inwardly extending integral flanges, louver slats secured between the plates and in the same plane, said slats having upwardly and downwardly inclined flanges extending in opposite directions, said flanges terminating in vertically disposed flanges engaging the inwardly extending portions of the integral flanges carried by the registering plates of the panel.

4.. The combination with a louver opening secured between the registering sections of the panel, said louver slat bodies having angularly disposed flanges, said angularly disposed flanges; engaging the angularly disposed flanges of the panel plates.

5. An article of manufacture, a louver panel formed from registering plates having openings therethrough, louver slats having portions secured between the registering plates, the marginal edges of said openings through the registering plates being provided with offset flanges and offset flanges carried by the louver slats and engaging the offset flanges of the plates.

6. A. louver panel formed from plates having openings therethrough, said plates'having offset flanges around the openings therein, louver slats in saidopenings, said slats having centrally disposed portions in a vertical plane and secured between the panel plates, said slats having offset portions engaging the offset flanges of the panel plates.

7. An article of manufacture, a louver panel comprising registering plates having marginal off-set portions, a plurality of slat-s having their ends secured between said registering plates, and flanges extending from said slats and between said marginal off-set portions in overlapping relation to the adjacent slats.

8. An article of manufacture, a louver panel comprising registering marginal plates having off-set flanges, and louver slats having their ends secured between said plates, said slats having flanges projecting therefrom within the planes of said ofl-set flanges. i

9. An article of manufacture, a louver panel comprising registering marginal plates having oppositely directed off-set flanges formed on the inner edges thereof, and louver slats having the ends secured between said plates, said slats having flanges projecting therefrom within the planes of said ofl set flanges.

10. An article of manufacture, a louver panel comprising registering marginal plates having oppositely directed off-set flanges formed in the inner edges thereof, and louver slats having their ends secured between said plates, said slats having oppositely directed off-set flanges projecting therefrom within the planes of said off-set flanges.

11. A door panel comprising registering margin plates having ofl-set 'flanges on the inner side thereof forming a channel, louver slats having their ends secured between said plates, oppositely directed inclined flanges carried by said slats, and vertical flanges carried by said inclined flanges, the inclined and vertical flanges of adjacent slats being disposed in overlaping relation.
